hydrocarbon resin 仅含碳、氢两种元素的单体经聚合而成的高分子聚合物。包括聚乙烯、聚丙烯、聚苯乙烯等通用合成树脂以及来自煤焦油 馏分、石油裂解馏分及松节油衍生的相对不纯单体聚合所得的古马隆-茚树脂、环戊二烯树脂、石油树脂、萜烯树脂等低分子量聚合物。前者产耗量大,构成热塑性塑料的主体;后者不能单独使用,适宜作沥青和地板的胶黏剂、橡胶和塑料的加工助剂、涂料和油品的添加剂等。
本发明的聚烯烃类树脂发泡体具有优异的柔软性和缓冲性,并且具有良 好的加工性,尤其是优异的切割加工性。
The polyolefin resin foam is excellent in flexibility and cushioning properties, and has good processability, particularly excellent trimming processability.
该剥离层(12)通过将包含有机硅与烯烃类聚合物化学结合的有机硅改性聚烯烃类树脂的剥离层成形材料挤出成形而得到。
The release layer 12 is formed by extruding a release-layer forming material containing a silicone-modified polyolefin resin in which silicone is chemically bonded to the olefin polymer.
由于石油的主要成分包括饱和烃、芳香烃类化合物、沥青质、树脂类等,这些物质难以降解,并且对水生生物有毒杀作用。
The main components of oil are saturated hydrocarbons, aromatic compounds, asphaltenes, resins, and so on. It is difficult to degrade these substances which are bad for aquatic life.
